Interface mechanical damage mechanism in machining carbon fiber-reinforced plastic/Ti stacks based on a three-dimensional microscopic oblique cutting model

Changping Li et al.

Summary: A three-dimensional microscopic finite element oblique cutting model was established to investigate the material removal process and damage formation mechanism in the interface zone when machining stacks of carbon fiber-reinforced plastic (CFRP) and Titanium (Ti) alloy. The process of fiber removal and damage formation, as well as the significant effects of fiber orientation and cutting sequence on subsurface damage formation in the interface zone, were explored and described in detail. An experiment was conducted to verify the simulation results, showing good agreement between the simulated machined surface morphology and experimental results.

A critical review of the drilling of CFRP composites: Burr formation, characterisation and challenges

Daniel Istvan Poor et al.

Summary: This paper reviews recent key papers on burr formation, measurement, and evaluation in CFRPs in an attempt to standardize and classify burr characterization related expertise. It is found that while burrs usually do not weaken the strength of composite materials, it is still recommended to remove them, especially since the deburring process often leads to significantly increased operation time and cost.

The interface temperature and its influence on surface integrity in ultrasonic-assisted drilling of CFRP/Ti stacks

Zhenyu Shao et al.

Summary: This study investigates the relationship between drilling temperature characteristics, heat damage, and surface integrity in Carbon Fiber Reinforced Plastic (CFRP)/Titanium Alloy stacks during Ultrasonic Assisted Drilling (UAD) and Conventional Drilling (CD). Results reveal a significant drop in interface temperature in UAD compared to a slight increase in CD, leading to reduced thermal damage and improved drilling performance in UAD. Through these findings, the study identifies ways to mitigate negative temperature effects in drilling processes of CFRP/Ti stacks.

Challenges in the fatigue crack growth characterization of metal/composite joints: A compliance-based investigation of a Ti/CFRP joint

Lucas Adamos et al.

Summary: This study thoroughly investigates the challenges and issues related to the fatigue crack growth characterization of dissimilar joints, focusing on multiple crack formation, suitable compliance, and strain energy release rate definitions. A new method for measuring experimental compliance in a Ti/ CFRP adhesive joint is proposed and compared to the dynamic compliance concept, while taking into account secondary cracking. Fatigue crack growth curves are extracted and discussed within the context of the aforementioned challenges.

Machining simulation of Ti6Al4V using coupled Eulerian-Lagrangian approach and a constitutive model considering the state of stress

Xiang Xu et al.

Summary: The accuracy of a machining model is dependent on its capability to describe physical phenomena associated with real machining systems. This study developed a high-speed machining model for a titanium alloy, considering factors such as strain hardening, strain rate, and temperature. The proposed constitutive model was compared with the Johnson-Cook model and experimental data, showing closer agreement with experimental results. The use of the Coupled EulerianLagrangian approach allowed for simulation of material side flow and the formation of lateral burrs on the workpiece.
